An orchid plant is growing on the branch of mango tree. How do you describe this interaction between the orchid and the mango tree?

1. Orchids, as epiphytes, rely on mango trees for support without causing any harm to them.

2. The mango tree, despite providing support, does not receive any benefits from this association with the orchid.

3. The interaction between the orchid and mango tree is characterized as commensalism, where one species benefits (orchid) while the other remains unaffected (mango tree).
